SystemDynamics: Systems Dynamics Library for Dymola/Modelica
Introduction
SystemDynamics is a graphical modeling methodology, designed in the
realm of Dymola/Modelica families of modeling tools. SystemDynamics
implements the approach to graphical modeling of ill-defined systems
that had been conceptualized in the sixties by Jay Forrester at
M.I.T.
The Systems Dynamics modeling methodology describes material flows
through a physically motivated system. State equations are being
obtained indirectly by the computation of material inflows and
outflows. Tabular functions are being used to model imprecisely known
and/or poorly understood phenomena.
The Systems Dynamics modeling methodology is particularly liked and
used by biologists and economists, who find its easily understandable
and mathematically non-challenging and non-threatening approach to
describing poorly understood systems appealing.
Historical Development
- SystemDynamics was developed in 2002 as a teaching tool for my
lectures on the mathematical modeling of physical systems.
- The library was updated in 2007 to the newest version of
Dymola/Modelica. At the same time, it was also completely
documented.
